VALVE 0R GATE.

. Application filed January 26, 19232. serial no. 531,995.

To all whom it may concern:

Be it known that 1, Fiunnnm'orr Sn'r'rma citizen of the United States, residing at iron Ridge, county of Dodge, and State of Wiscousin, have invented new and useful Improvements in Valves or Gates, of which the following is a specification.

This invention relates to improvements in' valves or gates such as are particularly adapted for use in the outlet ports of whey cans or cheese or milk vats. g

It is the primary object of this invention to provide a valve whereby more perfect sanitation can be obtained than has heretofore been possible. The discharge gates now in use ordinarily include a short length of pipe associated with the port with which the valve is to be used, and a valve member at the outer or discharge end of the pipe, the

J arrangement being such that when the valve is closed the pipe is inaccessible for cleaning purposes. Ithas also been impossible heretofore to remove the discharge gate from a jacketed vat without first draining the jacket as well as completely emptying th vat.

It is, therefore, more specifically the object of this invention to provide a discharge gate having a valve at its inlet end, whereby the whole interior of the device will be access ible at all times for cleaning purposes, even While whey or other material is in the vat; to provide a discharge gate so constructed that the portions thereof which carry the liquid discharged from a jacketed vat may be wholly removed and cleaned without disturbing the contents of the jacket; to provide a discharge gate having smooth and unobstructed interior surfaces, whereby cleaning is facilitated.

It is a further object of this invention to provide a discharge gate in which the valve seat, discharge pipe, and all the valve operating mechanism are constructed as a self contained unit to facilitate. the removal of these parts for cleaning, and to promote a. ,more convenient handling and installation of gates embodying this invention.

In the drawings:

Figure 1 shows a fragmentary section of a vet equipped with a discharge gate embodying this invention, portions of the gate and its operating mechanism being broken away to expose the interior construction. Figure 2 is a section taken on lint. 2--2 of Figure 1.

As apart of the discharge gate mechanism I prefer to provide a. fitting 6, which is provided with flanges 7 and 8, adapted to seat respectively against the end 2 and bottom 3 of the vatencircling the outlet port of the vat. Bolts 9 insure a fluid-tight connection between fitting 6 and vat l.

Fitting 6 is provided internally with two concentric sets of threads into the outer of which is screwed a tubular member 10. The member 10 is preferably threaded into the 3acket, and the nuts 11 and 12 threaded upon 'member 10 are turned up against the inner and outer faces respectively of the wall at of the jacket to prevent leakage at this point.

Into the inner of the two sets of threads with which the fitting 6 is provided is threaded the inletend oi discharge pi e 15, which has a downwardly directed out et portion 16. The lugs lagadapted to fit within the tubular member 10 to guide the disstem 19, which has an extended bearing at 20 in a boss or shoulder 21 which is formed upon the exterior of the downwardly curvmg Wall of pipe 15 adjacent its discharge portion 16. By means of the provision of the comparatively great bearing surface at 20 I am able to guide the valve without providing an additional support or" hearing member adjacent the valve seatwhere it would obviously interfere with, the fiowoi liquid thru the gate, with the-:ready removal of the gate for cleaning purposes and with the passage ofa; cleaning swab thru the gate. I consider it important therefore to have the valve 18 upon its valve stem ,19 supported and guided by a single bearing at 20, which is wholly without the space retubular operating lever 23 may be pivoted at 24. said lever being cut away to receive the block as shown. The block 22 is formed with a cam or beveled face 25 adjacent its outer side and an undulated portion comprising a series of saddles 26 upon its upper surface. The cars 27 carried by handle 23 support a lever 28 which is pivoted to them at 29, and extends thru an opening in the side of the tubular handle 23 into the interior of the handle. The free end 30 of lever 28 carries a smallroller 31 or similar device adapted to move with little friction upon the cam face 25, and over the ridges 32, which separate the saddle portions 26. Spring 34 within the tubular handle 23 bears against the free end 30 of lever 28 and foreesthe roller 31 into contact with block 22. A plug 35 threaded at 36 into the handle 23 provides means for adjusting the pressure of spring 34.

Pivoted to handle 23 and to valve stem 19 at 37 and 38 respectively is an L-shaped link or connecting member 39, which, may be provided, if desired, with forks at its ends for engagement with the designated parts. The arrangement is such that when the handle 23 is in the position shown in Figure 1 with the spring 34 forcing roller 31 against the cam surface 25, the handle will tend to move still further to the right and to maintain (thru link 39 and valve stem 1%),the valve 18 in a tightly closed position. f, however, the handle 23 be manually adjusted toward the left from the position shown in Figure 1, the roller 31, moving upon cam surface 25, will be forced upwardly against the pressure of spring 34 until it passes over the ridge 32, and comes to rest in the first of the saddles 26. The motion of handle 23 being communicated by the link 39 and han dle 19 to the valve 18, the tendency of the spring pressed roller 31 to remain in the first saddle portion 26 of block 22 will cause valve 18 to be maintained in a partially opened position. If the handle 23 be moved still further to the left to the position in which it appears in Figure 3, the spring pressed roller 31 will come to rest in the last of the saddle iportions- 26 of block 22, and the movement of the handle communicated thru link 39 and valve stem 19 will cause the valve 18 to assume a wide open position, allowing the contents of the vat to rush out thru the pipe 15 and be discharged downwardly from the outlet portion 16 thereof. If desired, screen 40 of any suitable form may be provided for insertion into the vat to screen the gate during the vat draining operation. 3

It will be obvious that the arrangement of the valve operating mechanism is such that it will not in the? least interfere either with the free passage of liquid thru the gate or with the removal or cleansing of those parts of the gate which are exposed to the contact of liquid passing therethru. If it is desired to clean the gate mechanism while the vat 1 is still full of liquid, the fact that the valve 18 is at the inner instead of the outer end of .the discharge pipe 15 permits the thorough cleansing of the whole length of pipe 15. After the vat 1 is empty and it is desired to clean the whole gate mechanism which is exposed to contact with the fluid from the vat including the valve 18 itself, the discharge pipe 15 may be unscrewed from the fitting 6, carrying with it as a unit valve 18 and its operating mechanism. It will be obvious that due to the provision of pipe 10 surrounding the discharge gate proper it will be unnecessary to drain or allow to escape from the jacket space 5 any fluid which may be contained therein.

It will be clear that the device herein shown and described is not only capable of performing all the functions for which it was designed, and satisfying the objects of this invention as hereinbefore specified, but has many other advantages in the particular service for which it is intended, and in many other connections as well. It will be found useful when applied to any container under circumstances, making sanitation particularly desirable.

When the outlet pipe or duct 15 is to be removed it is merely unscrewed and withdrawn. The operating arm or lever 39 may then be disconnected by Withdrawing the cotter pin and removing pivot pin 38 after which the valve and its stem may be with drawn and separately cleaned. *This leaves the bearing 20 open whereby a cleaning tool or brush may be passed thru it. In fact all 'the surfaces of-the pipe 15 are then unobstructed and may be very quickly and thoroughly cleaned.
